Abstract (en)
A composition for forming an electron emission source includes a polymer comprising a carbon-based material; a vehicle; and a unit of formula (1) below: wherein A 1 is a single bond, or a substituted or unsubstituted C 1 -C 20 alkylene group; and Z 1 and Z 2 are each hydrogen, a substituted or unsubstituted C 1 -C 20 alkyl group, a substituted or unsubstituted C 1 -C 20 alkoxy group, a carboxyl group, an -NR 1 R 2 group, a part of a styrene group resin, or a part of a novolac resin, and R 1 and R 2 are each hydrogen, a substituted or unsubstituted C 1 -C 20 alkyl group, or a substituted or unsubstituted C 6 -C 30 aryl group. An electron emission source may be formed from the composition for forming an electron emission source, and an electron emission device and an electron emission display device may include the electron emission source. When the composition is used to form an electron emission source, the printability of the composition is improved and thus repeated printings can be carried out. Also, the developing properties are improved, so that an electron emission device having fine patterns can be obtained.
